“…In many situations where people make choices, they might not have the information about all existing options for free. Acquiring and processing information can be costly in a wide range of empirical contexts: for example, school applications (Hoxby and Turner, 2015), housing and neighborhood (Bergman et al, 2020), hotels (Koulayev, 2014;Gu and Wang, 2021;Chen and Yao, 2017;Ursu, 2018), financial products (Hortaçsu and Syverson, 2004), insurance products (Brown and Goolsbee, 2002;Honka, 2014), credit market (Agarwal et al, 2020), TV channels (Yao et al, 2017), medical devices (Grennan and Swanson, 2020), automobiles (Moraga-González et al, 2018;Yavorsky et al, 2021;Murry and Zhou, 2020), other durable goods (Kim et al, 2010(Kim et al, , 2017Dong et al, 2020), and so forth.…”
